FASTENER-INSERTING MACHINE.

Patented Nov. 6, 1917.

Application filed July 26, 1915. Serial No. 41,874.

To all whom it may concern:

Be it known that I, STEPHEN A. DOBYNE,

a citizen of the United States, and residing at St. Louis, in the State of Missouri, have invented a certain new and useful Improve-.

from the insole edge than at the sides. Furthermore where a toe cap is used this curve or projection is enhanced by the stiff cap and by the additional thickness of the cap. Where the fastener seam is gaged by the contour of the insole, the gage must be shifted away from the horn when going around the toe in order to compensate for this additional projection of the upper. Furthermore it is desirable that the length of the fastener be increased when going around the toe in order to securely fasten the stiff and heavy toe cap.

One of the objects of this invention, therefore, is to provide a fastener inserting machine in which the gage is adapted to be shifted to one position when passing around the toe and to another position when passing along the sides, so as to compensate for the projection at the toe and form a uniform seam.

Another object is to provide a fastener inserting machine in which both the gage and the fastener supplying mechanism are capable of control so as to vary the position of the seam, and so as to also vary the length of the fasteners, during the operation of the machine.

Further objects will appear from the detail description taken in connection with the accompanying drawing, in which:

Figure 1 is a front elevation of a machine embodying this invention;

Fig. 2 is a side elevation;

Fig. 3 is a section on the line 3-3, Fig. 2;

Fig. 4 is a detail perspective view, and Figs. 5 and 6 are details showing the operation along the sides and around the toe respectively.-

The general type of machine to which this invention is shown as applied is shown in United States Patent Number 1,091,298, March 24, 1914, and is more particularly illustrated in my co-pending application, Serial Number 830,050, filed April 6, 1914. In the drawings hereinafter to be referred to, similar parts are designated by the same reference characters as in said application.

Referring, now, to the accompanying drawings, and more particularly in a general way to those parts fully illustrated and described in the application referred to, 10 designates a column or pillar which has mounted thereon a machine head 11, provided with a driving shaft 12, which driving shaft has mounted thereon a series of cams for operating different parts of the machine. The machine is also provided with a horn 23, adapted to receive and support the shoe. An awl bar 42 carries an awl 55,

which forms fastener receiving openings the driver to drive the same into the work.

The member 95, which carries the guide 97, is rigidl mounted on the end of a shaft 96, which passes through a hollow sleeve or shank 7 0 on the throat, so as to oscillate concentrically with the throat. A sprin stop plate 99 is mounted on an arm 100 o the member 95, and this plate bears agalnst the guide 97 to form a stop for the nail strings.. A pin 102 ismounted on a pr jecting arm on the member 95, and engages one end of a spring 103, the other end of which is attached at 104 to the machine head.

The shaft 96 is reduced in diameter at 105, and has rigidly mounted thereon a spool or collar 106 engaged by the forked end 107 of a shift lever 108 which is. pivoted at 109 on a bracket 110 having gears 111, whereby it may be secured to the machine head y scre s 112. A wedge shaped to the under side of the lever 108.

spring pressed slide block or plunger 114 is mounted in a bore in the bracket 110, so as to engage a wedge shaped block 115 880%Iiid 1s wedge shaped block 115 is adapted to be moved into engagement with either one of the screw stops 116 adjustably mounted in upwardly extending spaced lugs 117 on an extension 118 of the bracket 110. The screw stops 116 are provided with lock nuts to lock them in adjusted positions. A spring 120 bears, at one end, against the spool 106, and, at the other end, against the machine head. The parts so far described are fully shown and described in the above mentioned application.

A bracket a is mounted on-the column 10. and is provided with a guide receiving a gage b which is adapted to bearagainst the upper opposite the insole, of the shoe X mounted on the horn 23. The gage thus formsa sole edge gage. The gage is provided with a rack which meshes With a pinion on a shaft a mounted in the bracket (2, and this shaft has a downwardly projecting handle f whereby the gage may be adjusted. An upwardly extending arm 9 on the shaft 6 has connected thereto a link it whose threaded end extends through a sleeve 2' swiveled on the arm 108, and having nuts j'adapted to bear against the sleeve; the strings of connected nails are indicated at and Z, the strings having nails of different sizes. The welt c is guided under the presser foot 20 by a welt guide w fixed to the machine head, and, therefore, fixed with respect to the driver.

The fastener stock guide 97 can be shifted forwardly and backwardly to position either one of the fastener stock receiving grooves 98 in alinement with the driver passage and the cutter 133. Thus, in the position of parts as shown in the drawings, the left hand groove, Fig. 2, carrying the smaller nails, is positioned in alinement with the driver passage and the cutter. The gage b is, at this time, in its forward position, nearest the driver passage. The lever 108 is also, at this time, in position, with the wedge shaped block 115 in engagement with the forward stop, Fig. 3. The parts will be held in this position by means of the wedge shaped block 115, and the gage is also, of course, frictionall y held in the bracket a in the usual man nor, by providing the shaft 6 with a collar m and with nuts n, so as to clamp this shaft 'frictionally in the bracket a. The parts will thus be held in the position of adjustment.

Both the fastener stock guide and the gage can be shifted either by the operation of the lever 108 or of the arm f, so as to shift the other nail string, having the longer nails, into alinement with the driver passage, and so as to shift the gage back away from the driver passage. As the'parts are moved the mas er block 114.- will yield and will then snap on the other side of the block 115, so as to again secure theparts in adjusted position. Either of the grooves 98 may be alined with respect to the driver passage by the ad ustment of the proper stop 116, and this ad justment may be independent for each groove. Moreover, by the adjustment of the nuts j, the gage can be independently adjusted so as to occupy any desired position, and by adjusting these nuts so as to provide for a lost motion between the gage and the fastener stock guide, the gage may be moved any desired distance from zero to a maximum during the shift from one size fastener to the other, it being understood that this gage is held 1n position on account of its frictional engagement with the bracket. By placing the spring 120 between the guide shaft and the machine head the end play of the parts'is kept constant and on one side and in one direction. The shoe having been placed on the horn, and the welt in the welt guide, the operator proceeds to nail around the shoe. \Vhile nailing along the sides, the gage lies close to the driver passage, as shown in Fig. 5, and the fastener stock guide stands in position to hold the nail string 70 having the shorter nails in alinement with the throat and cutter, as shown in the drawings. When nailing around the toe, the gage is thrown out away from the driver passage so as to compensate for the projection at the toe cap, and simultaneously the fastener stock guide is shifted so as to place the nail string Z having the longer nails in alinement with the throat and the cutter. It is, therefore, insured that the welt will have a uniform projection with respect to the guiding base, namely the edge of the insole, and the seam will also be placed at a uniform position with respect to this base and the cutter. The capability of independent adjustment of the gage and the fastener stock guide enables the machine to accommodate itself to all classes of work. Thus it is sometimes desirable that the projection of the welt on the sides vary, as for difi'erent extension edges.

In such a case, however, it is not desirable to change the length of the fasteners. In accordance with this invention, this can be accomplished by the separate adjustment between the gage and the nail guide, and more especially through the capability for lost motion. By providing a certain lost motion between the nuts j on link it and the sleeve 7?, the gage itself may be shifted through certain limits before the lever 108 will be actuated to shift the nail guide. The operator can thus when operating along the sides shift the gage to provide, for instance, for a different extension along the fore-part than along the shank/or a still different extension along the ball than along the inside edge, the parts working at this time on the lost motion connection. When the toe cap is reached the gage can be shifted still farther to shift the nail guide to feed the longer nai be shifted during the operation of the machine, which, of course, is necessary when nailing around a shoe.

While the invention has been illustrated in connection with a welt attaching machine, it is obvious that it may be applied to a machine in which the outsole is directly attached to the lasted upper, the welt guide being in such a case removed.

Itis further obvious that various changes may be made in the details of construction Without departing from the spirit of this invention. It is, therefore, to be understood that this invention is not to be limited to the specific construction shown and described.
